It is possible to get access to nitrogen in antimatter chemistry before entering the nether.

There is only one model structure that can be put on the category of small categories for which the weak equivalences coincide with honest equivalences of categories. It's called the Joyal-Tierney model structure. You can define the suspension of an object in any model category as the homotopy pushout to two terminals, then define an abstract notion of a sphere in any model category by setting the 0-sphere as the coproduct of two terminals and the (n+1)-sphere as the suspension of the n-sphere.

A small category is a CW-complex if and only if it is a groupoid.

The great opera singer Enrico Caruso was the 18th of 21 children, only 3 of whom survived infancy.

Johann Sebastian Bach wrote an opera about coffee addiction.

The Russian composer Tchaikovsky was afraid his head would come off while conducting, so he would hold his chin with one hand while doing so.

The girlfriend of composer Erik Satie wore a corsage made of carrots, and she was a painter and liked to feed the paintings she made. Satie once threw her out the window but she survived.

My ICQ number...

1. This is true and remote from all cover of falsehood
2. Whatever is below is similar to that which is above. Through this the marvels of the work of one thing are procured and perfected.
3. Also, as all things are made from one, by the condsideration of one, so all things were made from this one, by conjunction.
4. The father of it is the sun, the mother the moon.
5. The wind bore it in the womb. Its nurse is the earth, the mother of all perfection.
6. Its power is perfected. If it is turned into earth,
7. separate the earth from the fire, the subtle and thin from the crude and course, prudently, with modesty and wisdom.
8. This ascends from the earth into the sky and again descends from the sky to the earth, and receives the power and efficacy of things above and of things below.
9. By this means you will acquire the glory of the whole world, and so you will drive away all shadows and blindness.
10. For this by its fortitude snatches the palm from all other fortitude and power. For it is able to penetrate and subdue everything subtle and everything crude and hard.
11. By this means the world was founded
12. and hence the marvelous cojunctions of it and admirable effects, since this is the way by which these marvels may be brought about.
13. And because of this they have called me Hermes Tristmegistus since I have the three parts of the wisdom and Philsosphy of the whole universe.
14. My speech is finished which i have spoken concerning the solar work

Hermeticism is the origin of most conspiracy theories if you dig deep enough. Truly the OG brainworm

All contradiction is reconciled above the abyss, hence why spiritual visions can sometimes appear horrible at face value.

Wait, what kind of esoteric did you mean?

The UK issued silver dollars once. They were dated 1804 and considered "bank tokens" as they had less silver than their denomination required at the time. They basically stamped a new design on Spanish colonial 8-real coins and passed them as five shillings.

The UK had a hard time with coin supply for most of the 1700s until 1816 when they finally downdized many coins.

I mean I've spent time studying occult stuff, so I guess pretty much the trope codifier.

Turns out they mostly just like to do the macarena. ¯\_(ツ)_/¯

Everything you learn from being active on Tumblr from late 2012 to now

We don't know if π+e is irrational.

The SR-71 used an Astroinertial Navigation System that used stars to keep the navigation information accurate as the plane flew over long distances. Normally an inertial navigation system degrades in accuracy over time and distance due to small errors building up and something called gyro drift. The NAS-14V2 used a catalog of known stars and a gimballed telescope to identify specific stars (even during a cloudy day) and determine the position of the stars in relation to the aircraft. Using this information the position of the aircraft can be used to revise the inertial navigation system's data every so often so the accuracy is much better.

Reign of Kings, a medieval online PvE survival game had a bug where the 360 rotation camera could be used in 3rd person mode to look inside of walls of other players. You could even access their chests if they built them against the wall (which they all did).

This meant that you could loot everyone’s bases without even breaking in. The game went through several major updates with this bug still in place. My brother and I used it extensively.

One day there is a major update and the release notes mention about how they have now finally fixed the “glitch where players items disappear from chests when placed near walls”.

Real G’s move in silence like lasagna.

T-rex is closer temporally to humans than they were to Stegosaurus.

Not sure if I can call this knowledge since I don't know if it's true, but I think I identified a couple of women from the 8th century CE who are mentioned in some Irish annals as actually being the same person. As far as I know there's next to no discussion of these women on the internet and there are basically no historical records of them, at least. So I guess if I'm right it's very obscure?

The women in question are Eithne ingen Bresail Bregh and Eithne ingen Cinadhon (and possibly also the legendary Eithne mother of Tuathal Techtmar)

There are two types of color E-ink displays:

One that uses a color filter on top of a regular black and white particle display, like in their Kaleido screens. This has a faster refresh rate like black and white displays, but the colors are muted and the screen’s “pure white” is much more gray than other displays.

One that uses four colored particles, cyan, magenta, yellow, and reflective white, like in their Gallery screens. This has a much slower refresh rate, but the colors are vivid and the screen’s “pure white” is just as good as a non-color screen.

There are also color transflective LCD screens from other companies that are sometimes marketed as “e-paper” or “paper like” that are fairly uninteresting.

And there are just straight up backlit LCD screens marketed as “e-paper” or “paper like” that are just not. XPPen just made one. I personally think this should be considered false advertising.

There is (or at least used to be) a debug command to write-protect a hard drive. No idea what it's for or why such a thing exists, but you flip a certain bit from 0 to 1 and drive no write. I won $100 once at work with this knowledge. We had a training course about how much better the new version of windows at the time was and how much harder it was to break - so hard they'd pay $100 (in early 2000s money) to anyone who could unrecoverably break their demo windows install during the 10 minute presentation. The instructor (who worked for Microsoft) said he'd been doing this for 6 months and they'd never had to pay out that prize before, much less 30 seconds in.

The most efficient base for a number system is e.

We use base 10 with 0-9 digits and each position is a ten's place, and the efficiency being measured is the product of the number of digits and the length of digits needed to represent a number in a given range of values. So if we used base 2 binary instead of base 10 decimal we only need to remember 2 digits 0-1, but to represent most numbers we'll need more digits, 11 in base 10 is 1011 in base 2. On the other side we could use hexadecimal to write shorter numbers like 11 is B, but need to use more digits, 0-F digits where A-F are the 10-15 digits.

If you try to plot a function that minimizes the efficiency the minimum is at e. So you'd have digits 0-2 and e would be written as 10 since each position is an e's place.

Human blood is a valid substitute for eggs in baking.

Hm, I guess this is esoteric in the sense that most people aren’t interested in it?

Some clothes are made with what’s called ‘slub cotton’, which is cloth made from cotton thread that has irregular lumps jutting out of it. It gives the final woven fabric an interesting look, almost like static. If it’s done with bright or contrasting colors it can give a really interesting pop to the final item.
